IPC: B41J2/175
Filed: 1987-04-15
Abstract: PURPOSE:To remove certainly occurrence of ink shortage in printing by a method wherein ink out preventive jetting is executed on each discharge opening of ink at intervals of a fixed time. CONSTITUTION:When one line content in printing is printed. A printing control device 20 transfers a recording head 12 to an ink out preventive jetting position C for a time T2 to execute ink shortage preventive jetting. The time T2 is set on a timer 23. When the time T2 has elapsed, a following time T1 is counted. When a time limit signal of the timer disappears, the printing control device 20 drives a pulse motor 14, makes the recording head 12 return to a home position B1, executes paper feed, and continues printing operation. When time has elapsed and the timer 23 automatically returns to an initial state again after counting (T1+T2) time from the initial state, the timer 23 generates the time limit signal again. And ink out preventive jetting of the recording head 12 is executed again. Thus, ink out preventive jetting is repeatedly execut ed at intervals of a set time even in printing operation.

Title: Formation of optical filter
Inventor: SHIBAYAMA MASAO
IPC: G02B1/113
Filed: 1986-04-22
Abstract: PURPOSE:To eliminate the spherical aberration of a dichroic mirror by carrying out a treatment in a heating state by utilizing the difference in coefficients of heat expansion between a substrate and a film laminated on the substrate, and letting the film part become flat when its temperature returns to the room temperature. CONSTITUTION:When a filter which has a dielectric multilayered film 6 on only one surface of the substrate 5 is formed, the film-adhered surface of the substrate 5 is formed in a concave shape. The film 6 is laminated while heated. Then, the substrate is placed at the room temperature, and consequently the surface becomes flat because of the difference in coefficient of heat expansion. Further, even when a filter which has a dielectric multilayered film on one surface of its substrate and a reflection preventive film on the other surface is formed, the filter can be so formed that the film surface becomes flat when put back at the room temperature by utilizing the difference in coefficient of heat expansion between the substrate and those films. Consequently, the spherical aberration when two linear polarized light beams which differ in wavelength are multiplexed and demultiplexed is eliminated.

Title: Driver for rotary exhaust valve of two-cycle engine
Inventor: IIO TOSHIMITSU
IPC: F02B75/02
Filed: 1978-07-31
Abstract: PURPOSE: To simplify the construction of an exhaust system and raise its durability, by providing a piston which is displaced by the discharge pressure of a lubricating oil pump and by applying the displacement of the piston to an exhaust valve.  
     CONSTITUTION: The oil pump P is rotated in connection with a crankshaft 3. The discharge quantity of the pump increases or decreases depending on the revolution speed of an engine A. The discharge pressure in a discharge passage 13 increases or decreases almost in proportion to the revolution speed of the engine. The discharge pressure is converted into the rotation of the exhaust valve 2 through a piston 24 and a rod 25. The top 1' of an exhaust port 1 is displaced up or down by the rotation of the exhaust valve 2 to automatically adjust the timing of exhaust. Since a section for detecting the revolution speed of the engine is integrated with a section for driving the driver for the exhaust valve, the construction is simplified and troubles are decreased.

Title: Operation control device for air conditioner
Inventor: SOGABE MASAHARU
IPC: F24F11/02
Filed: 1989-04-12
Abstract: PURPOSE:To reduce the number of components by a method wherein when a remote control switch is discretely set and varied for a controlling operation rather than its group control, a controlling operation in an air conditioner for a slave device address is changed over from a first controlling means to a second controlling means so as to enable each of the operating signals to be received. CONSTITUTION:When an operating signal or a set temperature signal is outputted from a concentration controller 2 and a remote controller 4, each of indoor devices 1, 1... is separately operated and discretely controlled. In turn, the remote controller 4 may display a set temperature or the like in the display means 7 for every indoor devices 1, 1. Even in case of this discrete control, a state signal outputted by the control means 15 for each of the indoor devices 1, 1... are received by the concentration controller 2 and the remote controller 4 and then the state is displayed in the display part 25 and the display means 27. Accordingly, as the remote controller 4 is changed over to be set to a discrete control from the group control, the control operation in the indoor devices 1, 1 in the slave device address is changed over from the control means 14 to the control means 15, resulting in that it is possible to reduce the number of components and to reduce the installing space for the components.
